I have been using this Nexthaus/Mobical sync solution for several weeks now and I LOVE IT!! The $40 that I had to pay for Nexthaus's Sync software is more than worth the peace of mind I have from knowing that my data are backed up. Mobical supports calender, tasks, and contacts. It does not back up email and notes, but I am more concerned about losing the three things it DOES back up. I would highly recommend this solution to anyone.
